Lγ Inequalities for the Polar Derivative of Polynomials
Malaysian Journal of Mathematical Sciences, 2023In this paper, firstly, we obtain an inequality in Lγ analogue concerning the polar derivative for a polynomial p(ξ) = Xm ν=0 cνξν of degree m having no zero in |ξ| < r, r ≥ 1 proved by Govil et al. [15]. Secondly, we also prove Lγ version for the polar derivative of an ordinary inequality for a polynomial having all its zeros in |ξ| ≤ r, r ≤ 1 ...

Ethene Copolymerization with Trialkylsilyl Protected Polar Norbornene Derivates
Macromolecular Chemistry and Physics, 2004AbstractSummary: The influence of the protecting group of polar norbornene derivatives and the structure of homogenous metallocene/MAO catalyst systems on the activity and the incorporation rates during ethene copolymerization reactions were studied. By varying the structure of the protecting group a relationship between the catalyst activity and the ...

Positive Integral Kernels for Polar Derivatives
2019The non-negativity on the unit disk of the real part of the polar derivative of a polynomial is proved via an integral representation with a positive kernel, or as a consequence of a weighted sum of hermitian squares decomposition.

Complete magnetic field dependence of
Signal amplification by reversible exchange (SABRE) is a promising hyperpolarization technique, which makes use of spin‐order transfer from parahydrogen (the H2 molecule in its singlet spin state) to a to‐be‐polarized substrate in a transient organometallic complex, termed the SABRE complex. In this work, we present an experimental method for measuring
